FEEDER FOR ORGAN-BELLOWS.

A SPECIFICATION forming part of Letters Patent No. 246,971, datedSeptember 13, 1881.

Application filed April 28, 1881. (No model.)

To all whom t may concern:

Be it known that I, REUBEN NicHoLLs, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented a new and usefulImprovement in Piston Bellows- Feeders for Organs, whereby escape-valvesin the piston trunk or cylinder may be automatically opened when thebellows becomes fully distended. l

I am aware it is not new to prevent overpressure in the bellows by anautomaticallyopened escape-valve; but such valves have, so far as Iknow, heretofore been generally located in the bellows, when so located,and the sudden partial collapse of the same when the escape-valve isopened causes a slight fluctuation in the feed to the pipes, and is therefore objectionable.

My invention corrects this defect by permitting the escape of surpluswind from the piston-chamber, and therefore avoids all disturbance ofthe wind in the bellows and wind-'trunks and chests.

My invention therefore consists, first, in a piston-feeder fororgan-bellows provided with automatic escape in or near the ends ofthepiston chamber or trunk, whereby the surplus wind is permitted to escapewhen the bellows becomes fully distended, and without checking themotion of the piston; second, in the system of levers andconnecting-rods whereby the distention of the bellows causes theescapevalves in the piston-trunk to open and permit the escape of thesurplus' wind.

That others may fully understand my invention, Iwill particularlydescribe it, having referenceto theaccompanyingdrawings,where- 1n--Figure lis a longitudinal section of my feeder and organ-bellows. Fig. 2is a transverse section ofthe same.

Ais theorgan-bellow's,constructed,Weighted, and communicating withwind-trunks F in the usual way. B is the piston-trunk, and C is thepiston moving therein, being actuated by proper and efficient power. D Dare the induction-ports, covered by valves in the usual way. E E are theeduction-ports, through which the wind is forced from the piston-trunkto the wind-trunk F, whence the conveyances G conduct and discharge itinto the bellows A. These parts'are all constructed as usual.

At the bottom of the pistou-trunk B, I make two or more ports, H, andcover the same with valves I, which when closed, prevent the escape ofany wind through the ports H H. These are the escape-valves in thepiston-trunk. It' they are opened, the wind forced by the piston willsimply escape 'by way of port I, instead of being forced into trunk F.There are many wa-ys offcausing said valves to open automatically; butthe method which I prefer is by means of the compound levers J, K, andL, which are collectively and simultaneously operated by the bellowswhen it reaches the period of comple-te distention. The levers J K arepivoted to standards b d, and at their proximate ends they are incontact, so that the depression of one may compel the depression of theother. The lever L is placed in a position transverse to the levers Jand K, and at its free end it rests upon the proximate ends of thoselevers. At its center said lever L is pivoted to a standard, e, and atits outer end it is connected to the top of the bellows by atension-rod, M, whereby said outer end of the lever L will be drawn upwhen the bellows approaches maximum distention, and by being so drawn upthe proximate ends of lever J and K will be depressed. The outer or freeends of said levers J and K are connected to the valves I I,respectively, by tension-rods w, so that when the bellows A approachescomplete distention, by means of the levers described or theirequivalent, the valves I I will be automatically opened, and the surpluswind will be permitted to escape without checking the movement of thepiston or disturbing the wind in the wind-chest S or bellows.

Having described my improvement, what I claim as new is-- l. Incombination wi th the bellows audwindtrunk of an organ and areciprocating feeder therefor, one or more automatic valves in saidfeeder, adapted to be operated substantially as described, whereby, whenthe bellows approaches complete distention, said valves will be openedand permit the surplus wind toN escape from the feeder without checkingthe motion of said feeder or piston, and without disturbing the wind inthe bellows or wind trunk and chests.

- 2. A reciprocating piston-feeder, B, and an organ-bellows, A,connected therewith, com- IOO bined with escape-valves I, arrangedwithin the feeders, connected with sald bellows, and adapted to operatein the manner described, so that the said valves will be opened by themovement of said bellows when the latter approaches complete distentiouand permit; the surplus wind to escape from the feeder.

3. The pston-trunk B, provided with the piston C and the escape-valvesI, combined with the bellowsAaud levers JK L,arranged 1o substantiallyas shown and described, and counected by tension-rods with said bellowsand eseapevalves, respectively, substantially as set forth.
